perhaps：“可能”，较为常用也较为正式的词，可能性也不十分大。它可以表示建议或要求，也可以表示以礼貌的方式下命令。I thought perhaps it was the letter you had been expecting. 我想这大概是你一直盼望的那封信。Perhaps you will kindly give us a hand when we are in trouble. 当我们陷入困境时，也许你会善意地帮我们一把。
probably：“很可能，大概”，可能性在这一组词中，表示一种几乎完全肯定的意思。He is the only witness of the accident; he can probably give us some detailed information about it. 他是这次事故的目击者，他大概可以告诉我们一些详细情况。There is probably some kind of living matter on some other worlds, but we do not know yet. 很可能在其他的世界存在着另类的生物，只是我们尚不知道。
5、mean, intend, propose
这组词都有“打算，有心做某事”之意。mean：“打算，想象，有...意图”，不如intend正式，强调心里想做的意思，但不强调决心。短语: mean...for 准备让...做...Everyone believed that it would be a very suitable match because John and Julia were obviously meant for each other. 每个人都认为他们的结合会很般配，因为约翰和朱利亚显然天生一对。He shouldn't have done it, of course, but he was thoughtless. And he meant to pay the money back. 当然，他本来不该那么做，但他考虑不周到，再说他是打算还钱的。
propose：“打算，建议”，指宣布或明确确定某人的意图，含有公开宣称
